## What is Interval Workout Timer?

Stop fighting your timer. Start building your workout.

Block Timer is a premium, modular interval system for those who have outgrown generic fitness apps. Whether you’re an athlete, coach, gym-goer, or home-workout warrior, Block Timer gives you the power to build any routine exactly how you want it.

The "Building Block" Advantage
Most timers are rigid—ours is flexible. Every exercise and rest period is a "Block" that you can color-code, name, and rearrange with a single swipe. No more "Set/Rest" constraints. Build complex circuits in seconds.

Core Features:
• Quick Timer: Set and go for simple sessions.
• Drag & Drop Builder: The most intuitive routine editor on the App Store.
• Smart Voice & Haptics: Audio cues read your exercise names aloud so you can stay focused.
• Instant Flexibility: Tap the +15s button mid-workout to extend any block without pausing.
• 100% Offline & Private: Your data stays on your device.
• Seamless Audio: Play music or podcasts without volume ducking or interruptions.
• Pro Stats: Track your total volume, activity days, and workout history.

Why Athletes Choose Block Timer:
"Finally, a timer that respects my routine. I can build specific mobility flows and high-intensity circuits without fighting a cluttered UI."
